The battery supplies power to the bulb and air compressor; and the bulb emitting light intermittently to indicate position to a diver.

FIELD OF THE INVENTION

[0001] The present invention relates to air inflation cushion, and particularly to an air inflation cushion as a float ball used in dive.

BACKGROUND OF THE INVENTION

[0002] Referring to FIG. 1, in general, a diver is equipped with a hydroscope 20 and a respiratory tube 11 which is connected to the hydroscope 20. A top opening 110 of the respiratory tube 11 is exposed from the water. Moreover, one kind of respiratory tube 11 is connected with a float disk (or float ball) for indicating the position of the diver, as illustrated in FIG. 2. A float disk 10 is engaged at a top opening 110 of the respiratory tube 11. Thereby, the respiratory tube 11 can be continuously exposed from water surface and can indicate the position of the diver. A distal end of the respiratory tube 11 is connected to the hydroscope 20, thereby, the diver breathing fresh air from the respiratory tube 11. However, the respiratory tube 11 is slender and thus can not supply sufficient air to the diver. Moreover, no illuminating device is installed to the floating disk. Thereby, in the dark, the diver can not be indicated clearly. Furthermore, seawater is waved so that the floating disk can be clearly shown as the diver is far away from the crowd.

SUMMARY OF THE INVENTION

[0003] Accordingly, the primary object of the present invention is to provide an air inflation cushion as a float ball used in dive. A battery and an air compressor are placed within the float ball. Air through hole of the air compressor are connected to a respiratory tube. A bulb, a battery, a plurality of vents and a control switch are formed on the float ball. The switch serves for controlling the bulb and the air compressor. The battery supplies power to the bulb and air compressor; and the bulb emits light intermittently to indicate position to a diver.

[0004] Moreover, a safety rope is installed beside the respiratory tube; one end of the safety rope being firmly secured to a bottom of the cushion and another end thereof being connected to a hydroscope. The safety rope is used as a safety device.

[0005] The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] With reference to FIGS. 3 to 4, the air inflation cushion as a float ball according to the present invention is illustrated. In the present invention, when the air inflation cushion is used as a float ball 10. The air inflation cushion may have a shape like an animal or other interesting shape. Other than a wind inlet 101, a bulb 90 and a control switch 100 can be installed at predetermined positions of the air inflation cushion. A receiving space 102 is formed within the air inflation cushion. A retaining frame 12 is formed for retaining the receiving space 102. The bulb 90 and the air compressor 70 are installed on the retaining frame 12. The battery 60 supplies power to the bulb 90 and the air compressor 70. The control switch 100 controls the operation of the bulb 90 and the air compressor 70. The air outlet of the air compressor 70 is connected to a respiratory tube 11. The operation of the air compressor 70 will suck air into the respiratory tube 11. Thereby, the diver can breath fresh air. Meanwhile, the bulb 90 on the float ball 10 will emit light intermittently for indicating the position of the diver. A respiratory tube 11 passes through the cushion and is adhered thereon by tapes so as to prevent water from draining into the cushion. A safety rope 13 is installed beside the respiratory tube 11. One end of the safety rope 13 is firmly secured to a bottom of the cushion. Another end thereof is connected to a hydroscope 20 for prevent accident (for example, the hydroscope 20 breaks, or the diver feels uneasy). Thereby, the diver may move along the safety rope 13 rapidly and air inflation cushion can be used as a life ring

[0014] Further, referring to FIGS. 5 to 7, another embodiment of the present invention is illustrated, wherein the float ball 10 is hollowed. The float ball 10 is formed by an upper and lower seats 30 and 40, and the two are screwed together. The upper seat 30 and lower seat 40 are formed with threads 300 and 400, respectively. A drain-proof washer 50 is installed therebetween so that the upper seat 30 and lower seat 40 are screwed tightly. The lower seat 40 has a retaining frame 12. The retaining frame 12 is installed with a battery 60 and an air compressor 70. The air output of the air compressor 70 is connected to a respiratory tube 11. A drain-proof washer 80 is installed between the respiratory tube 11 and the lower seat 40. A safety rope 13 is installed beside the respiratory tube 11. By the installation of the respiratory tube 11, when accidents occur (for example, the hydroscope 20 breaks, or the diver feel uneasy), the diver may move along the safety rope 13 rapidly. A top of the upper seat 30 is installed with a bulb 90 which can emit light intermittently. The edge of the bulb 90 is installed with a plurality of vents 301 and a switch 100 which controls the bulb 90 and the air compressor 70. The power of the bulb 90 and the air compressor 70 is from the battery 60. An inserted type connector 100 a is connected between the bulb 90, switch 100 and the battery 60 and air compressor 70 so that the assembly and detaching of the upper seat 30 and lower seat 40 can be executed easily.

[0015] In use, the inserted type connector 100 a is connected between the bulb 90, switch 100 and the battery 60 and air compressor 70. Then the upper seat 30 and lower seat 40 are screwed together to be formed as a float ball 10. Then the float ball 10 is placed in water and the switch is turned on. By operating the air compressor 70, fresh air is pumped into the respiratory tube 11. The bulb 90 on the upper seat 30 will emit light intermittently, the position is indicated to the diver.

[0016] The advantage of the present invention will be described herein.

[0017] i. The present invention-can be carried easily.

[0018] ii. The bulb emits light intermittently.

[0019] iii. Fresh air can be pumped automatically.

[0020] iv. The safety rope can be used in emergency.
